Actual capacity witnesses for the fresh driver path. The trace-generation input is Rohde--Schramm's existing input on the single canonical driver law. Deterministic uniqueness identifies the resulting measurable trace factor with the factor in the proved stopped trace law.

    Source documentation

    Evaluation on the canonical continuous-driver law is the same Brownian motion law, so the trace-generation input below is applied to a Brownian driver.

    Source documentation

    The same fresh path has an actual capacity witness and realizes the all-time finite-boundary restart identity. The only new instance of trace generation is its explicit specialization to the original driver path law.
